Swedish Hollywood-actor Stellan Skarsgaard will star in The Knight Templar - Svensk Filmindustri's $30.3m (Euro 22.8m) adaption of Swedish writer Jan Guillou's bestselling trilogy of Arn Magnusson - currently lensing on locations in Morocco.

Skarsgaard will perform as Arn's uncle in Scandinavia's so far most expensive film project - two features, directed by Denmark's Peter Flinth, with the first to be launched simultaneously in all Nordic countries in December 2007, the second scheduled for an autumn 2008 release.

Joakim Nätterqvist (Tsatsiki-Friends Forever) and Sofia Helin (Dalecarlians, Nina Frisk) play the leads in the depiction of Arn, born 1150, who is sent to the Holy Land as a Knight Templar, having succumbed to love and carnal lust. He returns to unite the then divided Sweden to become one country.

Skarsgaard's three sons, Gustaf, Bill and Valter, will also have parts in the film. Starring in Sweden's Generation Kplus entry, Kidz In Da Hood, Gustaf Skarsgaard is in Berlin as his country's Shooting Star. Svensk Filmindustri is producing with Denmark's Tju-Bang Film, and participation from Germany's Telepool.
